Young dancer battles rare 'stiff person syndrome'

NBC NATIONAL NEWS — Since she was young, dancing has always been Kayla Pounds' one true passion.

"I thought I would always have dance to get me through everything because dance doesn't die," Pounds said.

Through life's changes, she's always danced - until recently.

"My sister came home for Christmas, and she said, 'Why are you walking with your butt all out; you look stupid,' and I looked in the reflection of the building, and I was absolutely humiliated," Pounds said.

That was two years ago, and now the 20-year-old can barely walk at all. Even sitting down is a challenge, often requiring her mother's help.
